[j-nsp] Issue with MPLS VPN when using mixed LDP and RSVP Backbone !

[vaibhava varma]

Dear All

I was testing a setup whereby I am using mix of LDP and RSVP in the
backbone for transporting MPLS VPN Traffic. The setup is something as
below:

CE1--PE1------PE2/RR-------PE3----PE4------CE2

Now we have a limitation that we can only run LDP between PE4 and PE3.
>From PE3 to PE2/RR we have RSVP. From PE3 to PE1 we have LDP Tunneling
over RSVP.

Now the routes of CE1 are not getting installed into the VRF Table on
PE4. When checked the inet.3 table I do not see the route for PE2/RR
Loopback but only PE1 and PE3.
I tried to add a default static into inet.3 or importing the inet.0
rib to inet.3 on PE4 but still am not seeing routes.

I think the issue is that the BGP Next Hop is not in inet.3 for
PE2/RR. How can I achieve to make this setup working apart from
running LDP Tunneling over RSVP between PE4& PE2/RR or between PE3 &
PE2/RR.
